Efficient ammonia synthesis from nitrate reduction over a conjugated nickel phthalocyanine polymer in a wide potential and nitrate concentration range

The 2D-conjugated NiPcP exhibits highly efficient electrocatalytic NO 3 − to NH 3 conversion with 99.7% FE and maintains high FE across both a broad potential and a wide NO 3 − concentration range, offering sustainable NH 3 synthesis and water remediation.
